Coccidiosis in a Greater Slow loris (Nycticebus coucang)

Abstract

Since Eimeria pachylepyron was firstly described in slow loris (Nycticebus coucang) in 1972, there has not been any reports of the disease throughout the world. An adult male 0.8 kg bw greater slow loris (Nycticebus coucang) had diarrhea, emaciation and dead. Severe necro-hemorrhagic jejunitis with the presence of coccidian protozoa and secondary bacterial septicemia were the causes of death. Endogenous stages of E. pachylepyron were detected exclusively in the jejunal enterocytes especially in the crypt of Lieberkühn. The typical round unsporulated oocysts with homogeneous eosinophilic thick wall were closely related to E. pachylepyron. This is the first report to confirm the existence of the protozoan as the pathologic disease in the slow loris.
